如果確實需要,還可以在程序運行中動態(tài)定義一個數(shù)據(jù)塊。動態(tài)定義時,數(shù)據(jù)塊號是自動產(chǎn)生的,數(shù)據(jù)塊在存儲器中的位置是動態(tài)分配的。由于要定義的數(shù)據(jù)塊有可能大于CPU存儲器(用于數(shù)據(jù)塊的部分)的剩余空間,因此動態(tài)定義過程有可能失敗
2.訪問數(shù)據(jù)塊
在用戶程序中可能定義了許多數(shù)據(jù)塊,而每個數(shù)據(jù)塊中又有許多不同類型的數(shù)據(jù),因此,訪問時需要明確數(shù)據(jù)塊號和數(shù)據(jù)塊中的數(shù)據(jù)類型與位置。根據(jù)明確數(shù)據(jù)塊號的不同方法,可以用多種方法訪問數(shù)據(jù)塊中的數(shù)據(jù)。
直接在訪問指令中寫明數(shù)據(jù)塊號,如:
L DB5.DBW10
T DB10.DBW20
L Motor_1.Speed 符號地址
另一種方法是“先打開后訪問”。在訪問某數(shù)據(jù)塊中的數(shù)據(jù)前,先“打開”這個數(shù)據(jù)塊,也就是將數(shù)據(jù)塊號(數(shù)據(jù)塊的起始地址)裝入數(shù)據(jù)塊寄存器。這樣,存放在數(shù)據(jù)塊中的數(shù)據(jù)就可利用數(shù)據(jù)塊起始地址加偏移量的方法來訪問。如:
OPN DB5
L DBW10
OPN DB10
T DBW20
在打開一個數(shù)據(jù)塊時,先打開的數(shù)據(jù)塊會自動關(guān)閉(沒有專門的數(shù)據(jù)塊關(guān)閉指令)。由于有兩個數(shù)據(jù)塊寄存器(DB和DI寄存器),因此,多可同時打開兩個數(shù)據(jù)塊。一個作為背景數(shù)據(jù)塊,數(shù)據(jù)塊的起始地址存儲在DI寄存器中;另一個作為共享數(shù)據(jù)塊,數(shù)據(jù)塊的起始地址存儲在DB寄存器中。打開背景數(shù)據(jù)塊,在調(diào)用FB時可以自動實現(xiàn)。由于調(diào)用FB時使用DI寄存器,因此,一般不在FB程序中用OPN DI n指令打開數(shù)據(jù)塊。
3. 背景數(shù)據(jù)塊和共享數(shù)據(jù)塊
背景數(shù)據(jù)塊和共享數(shù)據(jù)塊有不同的用途。任何FB、FC或OB均可讀寫存放在共享數(shù)據(jù)塊中的數(shù)據(jù)。背景數(shù)據(jù)塊是FB運行時的工作存儲區(qū),它存放FB的部分運行變量。調(diào)用FB時,必須指定一個相關(guān)的背景數(shù)據(jù)塊。作為規(guī)則,只有FB塊才能訪問存放在背景數(shù)據(jù)塊中的數(shù)據(jù)。
一般情況下,每個FB都有一個對應(yīng)的背景數(shù)據(jù)塊,一個FB也可以使用不同的背景數(shù)據(jù)塊。如果幾個FB需要的背景數(shù)據(jù)完全相同,為節(jié)省存儲器,則可以定義成一個背景數(shù)據(jù)塊,供它們分別使用。通過多重背景數(shù)據(jù),也可將幾個FB需要的不同的背景數(shù)據(jù)定義在一個背景數(shù)據(jù)塊中,以優(yōu)化數(shù)據(jù)管理。各數(shù)據(jù)塊在CPU的存儲器中是沒有區(qū)別的,只是由于打開方式不同,才在打開時有背景數(shù)據(jù)塊和共享數(shù)據(jù)塊之分。原則上,任何一個數(shù)據(jù)塊都可以當(dāng)作共享數(shù)據(jù)塊或背景數(shù)據(jù)塊使用,實際上,一個數(shù)據(jù)塊由FB當(dāng)作背景數(shù)據(jù)塊使用時,必須與FB的要求格式相符。
